摘要： Immediately before transmitting a packet signal, a packet transmission base station (BS1) increases a target ISR of UL DPCH (S12), increases the TPC transmission power transmitted by the DPCH (S13), increases a power balancing reference power, and increases a DL DPCH transmission power (S14). In a mobile station (MS3), during packet reception, only a packet transmission base station (1) controls the UL DPCH transmission power (S15). This improves the reception quality at the base station (1) of HS-DPCCH including ACK/NACK and reduces the error ratio of the ACK/NACK signal.
摘要翻译：在发送分组信号之前，分组发送基站（BS1）立即增加UL DPCH的目标ISR（S12），增加DPCH发送的TPC发送功率（S13），增加功率平衡参考功率，并增加DL DPCH发送功率（S14）。在移动站（MS3）中，在分组接收期间，只有分组发送基站（1）控制UL DPCH发送功率（S15）。这提高了包括ACK / NACK的HS-DPCCH的基站（1）的接收质量，并且降低了ACK / NACK信号的误码率。

摘要： When performing base station selection type transmission power control, transmission of the dedicated physical control channel signal by non-transmitting base stations is halted while minimizing the impact on uplink transmission power control. This decreases downlink interference and increases downlink channel capacity. At a base station, reception quality measuring unit 506 compares the measured uplink reception quality with a target quality, forms a TPC signal on the basis of the results of this comparison, and communicates the contents of this TPC signal to transmission power controller 507. When the base station in question is a non-transmitting base station, transmission power controller 507 transmits the dedicated physical control channel signal only if the contents of the communicated TPC signal instruct a decrease, and otherwise halts transmission of the dedicated physical control channel signal.

摘要： In a cellular system, each mobile station concurrently linked to plural link base stations in soft handover state and receiving packet from the packet-transmitting base station controls a transmission power of an up-link dedicated physical channel based on a first transmission power control information included in down-link dedicated physical channels of the link base stations. In other state, the mobile station controls the transmission power based on a second transmission power control information included in a down-link dedicated physical channel of the packet-transmitting base station. This accelerates the power increase up to a target power level causing that the measured signal-to-interference-ratio at the packet-transmitting base station reaches a target signal-to-interference-ratio, thereby improving receiving quality of control signal from the mobile station at the packet-transmitting base station.

摘要： There is provided a mobile radio communication system which is capable of reducing a group ID in length with respect to the number of mobile stations and realizing efficiency of air resources. Suspend control of mobile stations is performed by notifying not only control information but also transmission/reception state update information for instructing a state [Active/Suspend] in a status update frame set in advance from a base station to the mobile stations using an HS-SCCH. The base station performs the suspend control by sending, in state update information at timing of a state update frame number of a user ID allocated in advance, a group ID of a user ID allocated to mobile stations desired to be made Active in advance.

摘要： Pluralities of state update frames are defined. The base station is configured to transmit a state update data to instruct the mobile station to be set to either an active state or a suspended state, in the state update frames. The base station is configured to transmit a packet only to the mobile station that has been set to the active state by the state update data. The base station notifies the mobile station of a packet transmission by transmitting a control data including a data necessary to receive the packet, earlier than the packet transmission by a predetermined time. The mobile station is configured to receive the control data and the packet when being set to the active state, and is configured to not receive the control data and the packet when being set to the suspended state.

摘要： To provide a cellular system for enhancing precision of judgement by rendering the number of code words to be judgement candidates at a base station as small as possible and thus improving the efficiency of using the code words.A base station control unit notifies the base station of the maximum number of the base stations on which a mobile station may set up links to allow the base station to limit the code word judgement candidates that may be received. Accordingly, it is possible to increase the distance between the codes among the code words to be the judgement candidates, consequently allowing the base station to reduce judgement errors of the code word.
